Detailed implementation manners

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Embodiment 1 Please refer to Figure 1 - Figure 8, the present invention provides a technical solution: an amphibious intelligent flood control and emergency rescue device, including a body 1. The front and rear sides of the body 1 are designed with a hollow interior. Multiple amphibious wheels 2 are connected to the lower ends of the front and rear sides of the body 1 through a steering mechanism and a motor. First chutes 3 are provided on the inner front and rear walls of the body 1. An installation plate 5 is slidably connected to the inner sides of the two first chutes 3 through two first hydraulic cylinders 4. A second chute 6 is provided on the upper left side of the installation plate 5. The two installation plates 5 are symmetrically arranged. The two second chutes 6 are designed as arc-shaped structures. The center of the arc of the second chute 6 corresponds to the center of the convex columns on the opposite inner sides of the two installation plates 5. A first slider 7 is slidably arranged inside the second chute 6. A bench 10 is connected to the opposite inner sides of the two first sliders 7 through bearings. The first slider 7 is slidably connected to a slide rod 8 through a convex block on the right side of the outer end. The right side of the slide rod 8 is connected to the upper right side of the installation plate 5 through a second hydraulic cylinder 9. The opposite inner side walls of the two installation plates 5 are rotatably connected to the bench 10 through convex columns. On the left and right sides of the inner bottom of the bench 10, a slope plate 12 is slidably connected through a first electric push rod 11. A horizontal sensor 16 is installed at the center position of the inner bottom of the bench 10. Third chutes 17 are provided on the front and rear sides of the bottom of the bench 10. An active component 13 is arranged between the left and right inner walls of the bench 10. The two slope plates 12 are symmetrically arranged. The notches on the opposite inner sides of the two slope plates 12 are used for limiting the horizontal position of the active component 13. A fixing component 14 is arranged at the upper end of the active component 13. The fixing component 14 includes two fixing frames 141. The two fixing frames 141 are rotatably installed in the grooves at the upper end of the table plate 131 through convex columns. The two fixing frames 141 are oppositely arranged. The shapes of the two fixing frames 141 correspond to the grooves at the upper end of the table plate 131. Fixing plates 142 are connected to the notch positions on the front and rear sides of the two fixing frames 141 through bolts. The fixing component 14 is used for fixing the working machinery. The active component 13 is connected to a counterweight 18 through an adjusting component 15. The counterweight 18 is slidably arranged inside the third chute 17; When the working mechanical equipment drives onto the platen 131 through the slope plate 12, the two fixing brackets 141 in the groove of the platen 131 are pushed up and fixed by the fixing plate 142 to complete the limit fixation of the working machinery. Then, before the body 1 is launched into the water, the operator turns on the first hydraulic cylinder 4 through the controller. The first hydraulic cylinder 4 drives the mounting plate 5 to move upward in the first chute 3, and simultaneously adjusts the position of the platform frame 10 upward, facilitating the subsequent horizontal position adjustment of the platform frame 10. When the amphibious wheel 2 travels onto the slope section, the body 1 and the platform frame 10 start to tilt along with the slope. The horizontal sensor 16 detects the tilt of the platform frame 10 and sends a signal to the control device. The operating system in the control device turns on the second hydraulic cylinder 9 to move to the left, and pushes the first slider 7 to slide and adjust the position in the arc-shaped first chute 3 through the slide bar 8. When the first slider 7 adjusts the position, because the arc-shaped first chute 3 simultaneously moves upward in the slide bar 8, while the first slider 7 adjusts the position, it drives the platform frame 10 to make an adjustment in the opposite direction of the corresponding tilt amplitude, so that the platform frame 10 always maintains a relatively vertical position with respect to the weight direction, and the working equipment and materials always remain in a horizontal state.

[0020] Embodiment 2 On the basis of the above, please refer to Figure 1 - Figure 8 As shown in, an active component 13 is arranged between the left and right inner walls of the platform frame 10. The active component 13 includes a platen 131. The platen 131 is rotationally installed on the inner side of the platform frame 10 through the central convex columns at the front and rear sides. The platen 131 is slidably connected to the fourth chute 132 through the left and right symmetrically positioned convex columns at the front and rear sides. The fourth chute 132 is opened on the front and rear sides of the platform frame 10. The fourth chute 132 is designed as an arc-shaped structure. The arc circle of the fourth chute 132 corresponds to the center of the central convex column at the front and rear sides of the platen 131. A fixing component 14 is arranged at the upper end of the active component 13. The active component 13 is connected to a counterweight 18 through an adjusting component 15. The adjusting component 15 includes two first oil tanks 151. The two first oil tanks 151 are installed on the left and right sides at the bottom of the platform frame 10. The inner sides of the two first oil tanks 151 are slidably connected to a first plug body 152 through springs. The upper end of the first plug body 152 is slidably connected to the grooves at the left and right sides of the bottom of the platen 131. The two first oil tanks 151 are connected to a second oil tank 153 through pipelines. The two first oil tanks 151 are designed as arc-shaped structures. The radian of the two first oil tanks 151 corresponds to the radian of the fourth chute 132. The left and right first oil tanks 151 are respectively connected to the left cavity and the right cavity in the second oil tank 153 through pipelines. A second plug body 154 is slidably connected to the inner side of the second oil tank 153 through a spring. The left end of the second plug body 154 is connected to the counterweight 18. The adjusting component 15 is used for adjusting the position of the counterweight 18. The counterweight 18 is slidably arranged inside the third chute 17; When the long-arm working machine is performing excavation, cleaning or handling operations, the different weights at the working end of the long-arm machine cause the platen 131 to drive the working machine to tilt at different amplitudes inside the gantry 10. At this time, the platen 131 slides and tilts in the fourth chute 132, squeezing the oil corresponding to the tilt amplitude in the first oil tank 151 in the tilt direction into the second oil tank 153, so that the second plug 154 pushes the counterweight 18 to adjust to the corresponding position, keeping the body 1 relatively horizontal in the water.

[0021] Working principle: When using this amphibious intelligent flood control and emergency rescue device, the operator drives the working machinery onto the platen 131 through the slope plate 12. Then, the operator pushes up the two fixing frames 141 in the groove of the platen 131 and fixes them through the fixing plate 142 to complete the limit fixation of the working machinery. Then, the operator starts the motor of the amphibious wheel 2 through the control device and controls the steering mechanism inside the body 1 to drive the body 1 to an area of the slope section where it is easier to enter the water, and then adjusts the left side of the body 1 to the front end when going downhill.

[0022] Then, before the body 1 enters the water, the operator turns on the first hydraulic cylinder 4 through the controller. The first hydraulic cylinder 4 drives the mounting plate 5 to move upward in the first chute 3, and simultaneously adjusts the position of the gantry 10 upward, facilitating the subsequent horizontal position adjustment of the gantry 10. When the amphibious wheel 2 travels onto the slope section, the body 1 and the gantry 10 start to tilt along with the slope. The horizontal sensor 16 detects the tilt of the gantry 10 and sends a signal to the control device. The operation system inside the control device turns on the second hydraulic cylinder 9 to move to the left, and pushes the first slider 7 to slide and adjust the position in the arc-shaped first chute 3 through the slide bar 8. When the first slider 7 adjusts the position, because the arc-shaped first chute 3 moves upward in the slide bar 8 synchronously, while the first slider 7 adjusts the position, it drives the gantry 10 to adjust in the opposite direction of the corresponding tilt amplitude, so that the gantry 10 always maintains a relatively perpendicular position with respect to the weight direction. When the body 1 gradually levels with the water surface after entering the water, after the horizontal sensor 16 detects that the position of the gantry 10 is gradually tilting, it sends a signal to the controller, and the system inside the controller turns on the second hydraulic cylinder 9 to move to the right to perform the reset adjustment of the position of the gantry 10; On the basis described above, when the machine body 1 transports the mechanical device to the working position and starts the operation process, for the long-arm machinery of the excavator type, during the operation, the change in the weight at the end of the forearm will cause the machine body 1 to be horizontally unbalanced. The operator needs to first turn on the first electric push rod 11 through the controller to push the slope plate 12 to move to the left and right sides, so that the limiting of the platen 131 is no longer carried out. At this time, when the long-arm machinery performs excavation, cleaning or handling, the change in the weight on one side of the mechanical long arm on the platen 131 causes the platen 131 to slide and tilt in the fourth chute 132 on one side of the gantry 10. The bottom groove on the tilted side of the platen 131 slides and abuts against the top of the corresponding first plug body 152, so that the first plug body 152 slides in the first oil tank 151, and the oil in the first oil tank 151 on the tilted side is squeezed into the cavity on the tilted side of the second oil tank 153 through the pipeline, and the second plug body 154 is caused to push the counterweight 18 to move in the third chute 17 in the direction opposite to the tilted side. During this process, the different weights at the working end of the long-arm machinery cause the corresponding volume of oil in the first oil tank 151 to be squeezed into the second oil tank 153, so that the second plug body 154 adjusts the counterweight 18 to the corresponding position.
